Frequently Asked Questions

What is the maximum depth rating for these underwater linear actuators?

The Linear Actuator – Self Compensated is rated to 3,000 msw (meters of sea water), while the Linear Underwater Actuator Trunion 1000N and the Linear Actuator 60,000 N Force are both rated to 6,000 meters depth. All models use oil-filled, pressure-compensated housings to maintain seal integrity and performance at these extreme depths.
